SEPARABLE BUTTON.

SPECIFICATION forming part of Letters Patent No. 238,043, dated February22, 1881.

Application filed December 10, 1880. (No model.)

To all whom it may concern Be it known that I, PHILIP H. LONG, ofNewark, in the county of Essex and State of New Jersey, have invented anew and useful improvement in Separable Buttons, of which the followingis a full, clear, and exact description.

Figure 1 is a sectional elevation of the improvement. Fig. 2 is asectional elevation taken at right angles with the section shown inFig. 1. Fig. 3 is an under-side View of the head and its shank. Fig. 4.is an under-side view of the foot and its shank. Fig. 5 is a plan viewof the inner side of the plate to which the tubular shank is attached.Fig. 6 is a plan view of the plate shown in Fig. 5 before the pointshave been bent up. Fig. 7 is a plan View of the spring holding and stopplate. Fig. 8 is a plan view of the footplate.

Fig. 9 is a perspective view of the spring. Fig. 10 is a perspectiveview of the button.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish separable buttons soconstructed that the head and foot can be readily connected anddisconnected, that the buttons will not turn in the button-holes, and inwhich the fastening mechanism shall be connected with the foot, so that0 any kind of heads can be used.

The invention consists in the combination, with the head and foot, in aseparable button, of a shank having a cross-head, a tubular shank havingsemi-tubular wings to receive 3 5 the ends of the cross-head, a platehaving notches and recesses to receive the ends of the cross-head, and aspring to hold the ends of the cross-head in the recesses of the plate,so that the parts of the button can be readily connected anddisconnected, and will be securely held in place also, in thecombination, with the plate carrying the tubular shank and havingnotches and recesses, of the plate having a slot to receive the spring,and notches 5 to receive and serve as stops for the ends of thecross-head, to keep the spring in place and limit the rotary movement ofthe head and foot; and, also,in constructing a separable button with thelocking mechanism arranged in its foot, as will be hereinafter fullydescribed,

the button-hole. The end of the tubular shank to the back of which issoldered or otherwise secured a shank or post, B, havinga cross-head, 0,formed upon or attached to its lower end.

To the back of the head A, around the base of the shank B, is solderedor otherwise secured a ring-flange, D, to overlap the end of the tubularshank and prevent the cufit' or other article to which the button isapplied from getting in between the head A and the end of the tubularshank, and impeding the detachment of the button. E is the tubularshank, the cavity of which is made of such a size as to receive theshank B, and which has internallygrooved or semi-tubular wings F formedupon its opposite sides, to serve as ways for the ends of the cross-headO to pass through,'and as guards to prevent the button from turning in OE is secured in a hole in the plate G, which 7 forms the back of thefoot, and which has notches H formed in it, corresponding in shape andposition with the wings F, so that the cross-head G can pass through thesaid plate G.

In the plate G, upon the opposite sides of the hole formed through it,and midwaybe tween the notches H, are formed notches or recesses I, toreceive the cross-head 0 when the shank B has been turned one-quarteraround. Upon the opposite edges of the plate G are formed two points, J,as shown in Fig.6, which are bent up at right angles, as shown in Fig.5, to enter notches K, formed in the edge of the plate L, placed uponthe inner side of the plate G, to prevent the plates G L from turnin gupon each other.

In the plate L is formed a slot, M, in such a position as to be diagonalto the lines joining the notches H and the recesses I, as indicated inFig. 7.

In the plate L, upon the opposite sides of the slot M, and in suchpositions as to be directly over the notches H and recesses I of theplate G, are formed notches N 0, to receive the ends of the cross-headO, and serve as stops to prevent the shank B from being turned fartherthan a quarter-revolution.

P is the spring, which is slightly curved, and is placed in the slot Min such a position I00 that the end of the shank B will rest against theconvex side of the said spring.

Q is the cap or .outer plate or foot, the edge of which is turned over,as shown in Figs. 1 and 2, so as to rest upon the back plate, G, andfasten all the parts of the foot together.

To connect the parts of the button the shank B is inserted in thetubular shank E, and the head and foot are pressed toward each otherwith sufficient force to compress the spring P, and are then turnedthrough a quarter-revo lution, to bring the ends of the cross-head Ginto the recesses I, where they will be held by the elasticity of thespring P. The parts of the button are disconnected by pressing the headand foot toward each other and then turning one or the other of the saidparts through one-quarter of a revolution.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. In a separable button, the combination,

with the head A and foot G, of the shank B, ha ing cross-head O, thetubular shank E, having semi-tubular Wings F, the plate G, havingnotches H and recesses I, and the spring P, substantially asherein'shown and described, whereby the head and foot can be readilyconnected and disconnected. and when connected will be securely held inplace, as set forth.

2. In a separable button, the combination, with the plate G, carryingthe tubular shank E, and having notches H and recesses I, of the plateL, having slot M, to receive the spring P, and notches N O, to receiveand serve as stops for the cross-head O, substantially as herein shownand described,whereby the spring is kept in place and the rotarymovement of the head and cap is limited, as set forth.

PHILIP H. LONG.
